MG MGB Technical - Later B under radiator shield
|I have no idea what that part is called but on later Bs there was a cardboard shield piece that fits across the chassis rails sort of under the bottom of the radiator going to the front of the engine. I think it is made from some kind of pressed (waterproof) cardboard type stuff.|
What exactly does this piece do? Does it, or rather not having it, affect cooling at all?
|It was designed to help divert cool air to the radiator. The new replacements are made out of ABS plastic. RAY|
|"mudguard" dump it. you should see the 1980 model. I looked an a late US LE and the mudguard extended back under the motor. I could be wrong and probably am but I dont see how seperating the air flow from the lower front valence and the radiator grill makes any difference at all. I dumped mine with no ill effects so far other than I won't win a concourse.|

|Clausager mentions this piece on p67, calling it a 'mud shield'-"...filling the gap between radiator and engine."|
|My 1980 MGB has one -It was looking a bit Tatty so bought a replacement from MGOC still made from some form of pressed cardboard!! four fitting self tappers alomg the sides and one screw to the front crossmember under the motor|

|If it's aft of the radiator as I think you mean it simply shields muck from the front of the engine, and is actually counter-productive in getting rad heat out of the engine bay. Only fitted to 77 and later models with the forward-mounted radiator. But the one in *front* of the rad between that and slots in the valance (on those cars that have them) is a different kettle of fish. That *does* force air through the rad, and *does* make a difference. The one on my V8 was curved rather than rectangular, fitting a brace to force it to the same shape as the valance slots made a noticeable difference.|
